Remesh modifier with keyed physics
So i figured out how to do it. The keyed physics has a checkbox marked use timing. Once that is checked to sliders are enabled. Adjusting the time slider sets how long the particles will move. By setting it to a value of around, the particles move for 40 frames leaving 60 frames for the display of the object. So in my situation. I had to set the time for object B and it worked.
